AEG Not Firing
 

My A&K Masada isn't firing when loaded with bbs. (I've tried different mags, mid caps and high caps) It seems that the bbs aren't able to go through the hop up unit even though everything internally is upgraded. I also recently added a cnc feeding part. What's the probably cause of the problem?

uhhh... just because it's an 'internal upgrade' doesn't mean it will work.

need an entire list of parts that were changed and exactly what part and brand went back in.

the hop up unit is the Wii Tech CNC Hop up package.

Omg dude I had the same issue I just switched back out the wiitech feed system with the plastic one. It doesn't matter much either its just a feed tube

Did you do the upgrades yourself, or did a gundoc do it?

Gun doc, because my knowledge of internals and such are minimal.

so I can only assume it was feeding properly when it left his hands
And you added the feed tube yourself afterwards?

Gun was working before then the stock feeding nozzle broke. replaced it with a new one and now it isn't firing.

Well then I figure it's the gundoc's fault for not making sure it was feeding before sending it out
Bring it back to him, tell him it's not feeding

I did send it back to him, and it is not firing at the moment, he says there's something wrong with the hop up unit now

Turn the gun upside down, put BBs in the feed tube. If it feeds, it's mag vs hop-up unit feeding issue, if not, it's most likely the nozzle that causes the problem (too long,disconnected,...)
